SM said he used a bit of old lamp or speaker wire. That tends to come as a pair sometimes fig 8 with a slight twist. He said the thinner copper stuff works just as good as thick chunky cable. If his notes are true and uniform throughout the model range (probably not) there should be 3 control coils and 3 collectors although collectors can easily be 1 + 2.

You should ask Mannix to send you the decent quality vids im sure he has the full Xmas box set in HDTV.

Hi all!

@Wattsup,

well after my post I went to my workbench and I did the following test: just coiled 20 mt of my 40 leads Litz wire  (coil diameter = 10 cm on air) soldered all the leads together on both ends and connected them to my scope  (so not serializing anything for now).

Then SLIDED a 1cm x 4 cm ceramic bar magnet over.

YOU KNOW WHAT HAPPENED: ABOUT 0.3 V peak to peak DC output!!!!!!!! with a fdo just following the magnet movement....FAR SUPERIOR TO ANY ASPECTATIVE!!!

So CHARGED by that fact I took an old air coil I used for spark experiments (coil with 500 turn of 0.25 mm enameled wire) and did same tests, results:

AS BEFORE BUT WITH  ALMOST 0.7V


Then I put two magnets: on coil top & bottom: the effect is still enhanced: about .9V output

Conclusion for now: it's my opinion that it's not difficult at all to obtain kicks without any external supply...just use a magnet.  It worths to build on the Wattsup idea to inject output signal on some Litz leads in order to obtain quickly a sort of regeneration=kick multiplication.

It is possible if you want to show some pics about said tests.

@ all
next step IS TO FIND THE CORRECT WAY TO USE THE MAG GENERATED KICK!  please do expose yours ideas  as I can check them quickly!

Hello all,

@Roberto,

Hello all,

I need to clear up a bit of confusion that I have. But first I would like to relate an experience from my youth.

When I was younger I would build these massive coils with as much inductance as possible. I would then connect a 9 Volt battery and get the magnetic field to full strength. Now when the voltage to the coil was cut the field would collapse and I would get a large back EMF tens of times the voltage used to create the field. This was great for terrorizing unsuspecting younger siblings and small animals. (I had too much fun.)

I knew this back EMF as a "Kickback" or "Back-kick"

My question is; is this back-kick the same as the kicks that SM talks about. And also, and not separate from, are SM's "kicks" also what is generally known as "overshoot" and "undershoot?"

Just trying to make this as clear as crystal.
